Content that is cached on DC's can be delivered even faster to browsers by compressing the content before sending. Unlike other compression solutions on the market today, a given image or page is compressed only once and served over and over again instead of compressing on the fly which wastes CPU cycles and might end up being slower than if there were no compression at all. Compressed content is only sent to clients that already support compressed encoding as most browsers already do today. No client-side downloads or plug-ins are required to use this feature for most content.
